Subject: Re: ports/185182: x11/xorg of 10-RC2 has blank screen on APU-3400 system<= br>

=0AThanks for your fe= eedback.

When you used FreeBSD 8.x, do you remember if you used Rade= on or VESA
driver? Because your integrated GPU is fairly recent and it's= surprising
if it was supported on FreeBSD 8.x.

On FreeBSD 10, I = suggest you follow these instructions to use the new
Radeon driver:
&= nbsp; https://wiki.freebsd.org/Graphics#Installing_KMS_Ports<= br>
You'll end up with a newer X.Org server/drivers and libGL. They supp= ort
your card.

There's one caveat with this new driver: once an X= session is started,
you won't be able to use the console anymore. That = means that
VT-switching with Ctrl+Alt+Fx and exiting from X.Org will onl= y give you
a black screen. If this is unacceptable for you, keep using V= ESA.

Now, about your input devices problem: xorg-server is built wit= h HAL by
default. You have to enable hald (hald_enable=3D"YES" in your
/etc/rc.conf) so that X.Org server can aut= odetect your input devices.
And you don't need an xorg.conf file to conf= igure them in this case.
